Abstract:
A motor includes a rotor including a shaft extending axially, a stator surrounding a radial outside of the rotor and including a coil defined by a wound coil wire, a holder disposed on an axially upper side of the stator, the coil wire being inserted into the holder, the holder including through-holes extending axially, and a circuit board disposed on the axially upper side of the holder, an electronic component being mounted on the circuit board. When the holder is viewed from the axially upper side, the through-holes are located in a region where a center angle (α) centered on the shaft is less than or equal to 180 degrees.
